Never mind I manage to get the mechbox back into the lower receiver. The levers/sprockets/whatever you call it does take a fair bit of wiggling around. :banghead:

Stock barrel is dirty - definitely needs to be cleaned before use.

Hop-up is 2 piece - not too impressed, as 2 piece hop-up unit is much easier to leak air then 1 piece hop-up. That said, they are using a SR25 nozzle so hopefully leaked air is kept to a minimum.I believe someone from filairsoft.com manage to mod his Masada to take a Systema hop-up unit?
